Bacteria biofilm

This confocal micrograph, taken as part of a synthetic biology project, shows Bacillus subtilis, a Gram-positive, rod-shaped bacterium that is commonly found in soil. Distinct lineages of bacteria expressing different fluorescent proteins were initially mixed randomly on a petri dish. As the bac... Read More

Nipah virus virions, related to Hendra virus

This transmission electron micrograph (TEM) depicted a number of Nipah virus virions that had been isolated from a patient's cerebrospinal fluid (CSF) specimen.

Nipah virus is a member of the family Paramyxoviridae, and is related, but not identical to Hendra virus. Nipah virus was initially ... Read More
